Sean Prall – Immunity, Stress, and Development: The Role of Adrenal Androgens in Human Evolutionary Biology

Sean Prall: University of Washington School of MedicineThe developmental pattern of adrenal androgen production is unique to humans and chimpanzees, and this pattern is thought to have important implications in human evolutionary biology. Unlike other hormones, the ultimate role of adrenal androgens is not well understood despite the important physiological roles these hormones play. The […]

Paul Smaldino – Learning About Social Evolution with Extremely Unrealistic Models

Paul Smaldino: UC DavisThe lives of social animals, none more so than humans, are shaped by cooperative interactions. Sharing, exchange, and synergy are the name of the game. Understanding the origins of cooperative behavior with any clarity often requires formalization of theories in the way of mathematical and computational models. These models by necessity ignore […]

Mirta Galesic – Early Development of Human Cooperation: The Role of Interdependence

Mirta Galesic: Santa Fe InstituteThe importance and scale of cooperation in human societies is unmatched among other primates and is considered to be a major contributor to our species’ exceptional success. Given that cooperation seems so useful, it is surprising that it flourished only in humans but not in other primates who had similar cognitive […]

Jeff Winking – State of the Union: The Fate of the Paternal Investment Model of Human Marriage

Jeff Winking: Texas A&MFathering traditionally played a central role in the evolutionary stories of human marriage. Paternal investment proved a convincing lynchpin linking together numerous hallmark aspects of the human adaptive strategy: the capacity for long-term romantic bonds, altricial infancy, extended juvenile dependence, etc. However, recent theoretical work suggests that the importance of paternal investment […]

Chris Kuzawa – Brain Energetics and The Evolution of Human Childhood

Chris Kuzawa: Northwestern UniversityHumans are unusual in having a childhood stage characterized by a prolonged period of exceptionally slow growth. Many hypotheses have been proposed to explain why humans have evolved this life history stage. In this talk, Chris Kuzawa will discuss his recent collaborative work that quantifies the costs of human brain development and […]

Robbie Wilson – Costs and Benefits of Dishonest Communication: Parallels Between Cheating Crustaceans and Diving Soccer Players

Robbie Wilson: University of QueenslandAnimals routinely compete for access to limited resources, including food, territories or mates. Because combat is energetically costly and increases the risk of injury or death, individuals should avoid fighting unless they have a reasonable chance of winning. Specialised structures such as teeth, claws or horns can be used to show […]

Rose Scott – Can Babies Read Minds? False-Belief Reasoning in Early Childhood

Rose Scott: UC MercedA large part of our daily lives involves interpreting other people’s behavior in terms of their underlying mental states. In particular, the capacity to recognize that others may hold and act on false beliefs plays a vital role in social interactions. The question of when and how false-belief understanding develops is currently […]

Ed Vul – Do People Make Decisions Via a Bag of Error-Prone Tricks?

Ed Vul: UC San DiegoHuman behavior is robust, adaptable, and, human behavior often deviates from the utility maximizing "rational" agent. This is usually attributed to people relying on an assortment of cheap heuristics to make efficient, but frequently biased, decisions. While the heuristics and biases research program has highlighted the many deviations of human behavior […]

Jerry Siegel – Natural Sleep and Its Seasonal Variations in Three Pre-Industrial Societies

Jerry Siegel: UCLAHow did humans sleep before the modern era? Because the tools to measure sleep under natural conditions were developed long after the invention of the electric devices suspected of delaying and reducing sleep, we investigated sleep in three preindustrial societies. We find that all three show similar sleep organization, suggesting that they express […]

Athena Vouloumanos – How Early Perceptual Biases Shape Human Communicative Development

Athena Vouloumanos: New York UniversityLike many animals, human infants have biases for the vocalizations of their own species, preferring speech to many non-speech sounds just hours after birth. How do these early proclivities develop and how do they contribute to human communicative development? In her talk, Athena Vouloumanos will draw from behavioral and neural data […]
